Recombinant porcine IFN-gamma potentiates the secondary IgG and IgA responses to an inactivated suid herpesvirus-1 vaccine and reduces postchallenge weight loss and fever in pigs.

The effect of recombinant porcine interferon-gamma (IFN-gamma) on the immunogenicity in vivo of inactivated suid herpesvirus-1 (SHV-1, Phylaxia strain) was studied applying two successive i.m. immunizations.

Myocardial beta-adrenergic receptor characteristics in T(3)-induced ascites and in broiler lines differing in ascites susceptibility.

The present study was designed to investigate the myocardial beta-adrenergic receptor characteristics in T3-induced ascites in two genetic lines of broilers, in order to look for possible involvement of myocardial beta-adrenergic receptors in the development of broiler ascites syndrome. Myocardial membrane fractions were prepared from 6 and 8 week old chickens fed a 1.5 parts/10(6) T(3) supplemented diet from day 1 in order to increase ascites incidence.

Evaluation of parenteral vaccination methods with glycoproteins against Aujeszky's disease in pigs.

A comparative evaluation of vaccination methods with glycoproteins for the induction of immune responses and protection of the pig against Aujeszky's disease virus (ADV) was performed. Different vaccination routes (intradermal (i.d.

Pulsatility of plasma growth hormone and hepatic growth hormone receptor characteristics of broiler chickens divergently selected for abdominal fat content.

1. Plasma growth hormone (GH) pulsatility and hepatic GH receptor characteristics were compared in experimental lines of meat-type chickens selected for high (HF) or low (LF) abdominal fat content. 2.

Study of the hepatic growth hormone (GH) receptor at different ages in chickens selected for a good feed conversion (FC) and a fast weight gain (GL).

The influence of genetic selection for improved feed conversion (FC) and fast growth (GL) in broiler chickens, on the hepatic growth hormone receptor was investigated as a function of age. Selection for improved feed conversion resulted in lean chickens, whereas selection for fast growth resulted in fat chickens. Growth hormone receptor characteristics were determined in liver microsomal fractions and plasma GH concentrations were measured by radioimmunoassay.
